Preparation of Novel Polyaniline and Phosphoric Acid Doped Sulfonated Polybenzimidazole Composite Membranes for Fuel Cells

Polyaniline (PANI) and phosphoric acid (PA) doped sulfonated polybenzimidazole (SPBI) composite membrane was prepared for application in high-temperature proton exchange membrane (PEMFC) without the need of humidification. The synthesis and characterization of targed composite membrane were introduced in this paper.
